Final answer:
Rough stone chopping tools made by early Homo species are known as Oldowan tools. These were followed by the more advanced Acheulean tools and later by Mousterian tools, which all show progressive technological developments in human history.
Step-by-step explanation:
The rough stone chopping tools made by early members of the genus Homo are called Oldowan tools. These tools were used until about 1.7 million years ago and are characterized by their crude and primitive appearance, but they marked a significant leap in human engineering ability at the time. They served a variety of cutting, scraping, and chopping purposes, such as butchering meat and smashing bones to access marrow.
Following the Oldowan era, the Acheulean tools emerged around 1.7 million years ago, representing a more sophisticated technology. Shaped through the careful removal of smaller stone flakes to form teardrop-shaped hand-axes, these tools were far superior to the Oldowan variety and remained dominant until about 250,000 years ago.
Mousterian tools came into existence after Acheulean tools, introducing smaller hand-axes and specialized tools made from stone flakes. The advancement in stone tool technology continued to evolve, eventually leading to the production of blade tools and the use of a wider variety of materials, including bone and antler, during the Upper Paleolithic period.
